I recall there being SMS emulators for the original PlayStation, but they were abysmal at best.. I would maybe think it would be a better idea to start smaller. Maybe the 2600 or something along those lines?

the problem with emulators on consoles and in general is usually the programmers are too interested in emulating the hardware perfectly instead of getting the games to run even if they have to cheat. What would be even cooler than just another console emulator would be pick out the top ten best NES games ever and give them 3DO make overs.

I suppose to ride on that thought, someone physically ported Super Mario Bros. to the Sega Genesis. It's pretty much identical to the NES game. I have no doubt that the 3DO is less similar to the Genny than the Genny is to the NES, so I'm not sure how easily doable that is, but it would sure make for a neat experiment.

and people are constantly porting 16bit and 32bit era games down to NES so why can't it go the other direction? I think it goes back to the 3DO not having the same following as Sega and Nintendo which is why you see Sonic on SNES and Mario on Sega but and everything else showing up on NES even Super Mario World was ported. I do not know what the specs for 3DO are or how you would even go about it but I am sure it can be done just nobody cares enough to do it.
